feat: add structured logs to application output

This commit removes the default Uvicorn loggers in favor of a structured, JSON log formatter that includes a correlation ID and duration_s field. This log could be ingested to Elasticsearch for analysis and searching.

Relates to #25 (closed)

Example logs:
